Went to change my rear pads today and somehow the rear calliper bolt is now rounded off, what size bolt is it? I was using a Torx bit, is the correct? I did the other calliper fine last weekend but this caliper I can't get the bottom pin off and now I've found out I've rounded the top caliper bolt. Also the caliper moves slightly when I push it as I think I undid the bolt a bit before I couldn't move it anymore. Is this going to be dangerous?

I'm having trouble getting the bottom pin out though, been wacking it with a centre punch but it won't move, but if I got the pads out I still wouldn't be able to get the rounded Allen key bolt out would I?

To change pads on Rear don't need to remove the top and bottom slider bolts.
If the fitting kit pins are seized in they can be drilled out and new ones fitted.
Your rounded off top slider bolt will be a problem if you need to change disc.
